TWO-LIQUID MIXTURE COLD CURING TYPE PAVEMENT MATERIAL AND ELASTIC PAVING METHOD
To provide a two-liquid mixture cold curing type pavement material which exhibits excellent physical properties of cured products and workability to sufficiently suppress foam during curing without the application of Ordinance on Prevention of Hazards due to Specified Chemical Substances.SOLUTION: A two-liquid mixture cold curing type pavement material according to the present invention contains: a main agent containing isocyanate group terminated prepolymer which is obtained by reacting a polyisocyanate compound containing 97 mass% or more of 2,4-tolylene diisocyanate with an active hydrogen group-containing chemical compound, and containing unreacted tolylene diisocyanate of less than 1 mass%; and a curing agent composed of an active hydrogen-containing chemical compound containing 90 mass% or more of dimethylthiotoluenediamine and not containing polyol chemical compound as residue, the residue being a polyamine chemical compound other than 3,3'-dichloro-4-4'-diaminodiphenylamine.SELECTED DRAWING: None
【課題】特定化学物質障害予防規則が適用されることなく、優れた硬化物物性と作業性を発揮し、硬化中の発泡が十分に抑制される２液混合常温硬化型舗装材を提供する。【解決手段】本発明の２液混合常温硬化型舗装材は、97質量％以上の2,4-トリレンジイソシアネートを含むポリイソシアネート化合物と、活性水素基含有化合物とを反応させて得たイソシアネート基末端プレポリマーを含み、未反応のトリレンジイソシアネートが1質量％未満である主剤と、90質量％以上のジメチルチオトルエンジアミンを含み、残部としてポリオール化合物は含まず、該残部は3,3’-ジクロロ-4-4’-ジアミノジフェニルアミン以外のポリアミン化合物である活性水素含有化合物からなる硬化剤と、を含むことを特徴とする。【選択図】なし
